The line of merchandise reflects the classic Americana aesthetic, with varsity jackets, sweatshirts, red-checkered white socks and hoodies available to buy.
Five Guys dropped the new merchandise online on Monday 4 July, on Independence Day in the US.
The collection ranges from black and white embroidered varsity jackets and branded sweatshirts to Five Guys milkshake T-shirts and bespoke beanies and baseball caps.
According to Five Guys, the varsity jacket pays tribute to Arlington, Virginia, where the brand was first founded in 1986.
Prices start from £10 for the socks to £75 for the varsity jacket. T-shirts cost £20 each, while sweatshirts are priced at £35 and hoodies at £45.
Each piece of merchandise also features the block graphics of the iconic Five Guys logo.
The collection arrives as varsity jackets and other collegiate Americana styles have become a must-have for fashion watchers.
One of the most prominent designers to have included varsity jackets was the late Virgil Abloh, whose final autumn/winter 2022 show for Off-White took place posthumously at Paris Fashion Week in March.
The designer, who died on 28 November 2021, featured a red and cream varsity jacket in his show, as well as a blue version.
Louis Vuitton’s menswear collection for autumn/winder 2022 also featured a purple and white varsity jacket with the letters LV emblazoned across them.
The jacket was later worn by A$AP Rocky in February as he posed with Rihanna and her then-growing baby bump during a Fenty Beauty event.
Rocky is a long-standing fan of the varsity jacket and regularly dons both vintage and new designer pieces.
Supermodel Bella Hadid was also recently spotted wearing a navy blue varsity jacket while out and about in New York City, as was Danish fashion stylist Emili Sindlev, who wore a navy and mustard yellow version to Copenhagen Fashion Week.
